The analysis of ethinyloestradiol in tablets by liquid chromatography with electrochemical detection

  • P. J. Kelly
  • P. A. Sewell


The analysis of ethinyloestradiol in tablets has been carried out by reversed phase high performance liquid chromatography (HPLC) using electrochemical detection. The drug was eluted with aqueous acetonitrile containing sodium acetate as background electrolyte. The mobile phase was used as extracting solvent, and 4-tertpentylphenol was used as internal standard.
